Beware, not nessesarily true, you have to take into account suits, eg, your holding 6h 6d and there is a raise before you act, you call hoping for a 3rd 6 to hit, meaning if some has an over pair or the board are all overcards, you have 2 outs. However, if the board is 3 spades, you potentially only have 1 out as the 6 spades will almost certainly give someone a flush, the 6 clubs is your only out. Be carefull in these situations.
